Jorge Eduardo Candelaria cbd9cb5de3 ASoC: twl6040: Increase timeout for power up
After coming back from suspend, the timeout waiting for Phoenix
chip to complete its power up sequence is not enough, which leaves
the codec cache value for some registers in an outdated state.

Increase the timeout value to wait for the power up sequence
to correclty complete.

Jorge Eduardo Candelaria f1f489a6aa ASoC: twl6040: Clear interrupt status at boot time
On Phoenix 1.1, the INTID register default value is an invalid
one, causing the interrupt handler to think the phoenix power on
sequence is ready before it actually finishes.

This causes some i2c errors when trying to configure twl.

Peter Ujfalusi a6cea9655b ASoC: tlv320dac33: Power down digital parts, when not needed
If the following scenario has been followed:
1. Enable analog bypass
amixer sset 'Analog Left Bypass' on
amixer sset 'Analog Right Bypass' on

2. Start playback
aplay -fdat -d3 /dev/zero

After the playback stopped (3 sec), and the soc timeout (5 sec),
the digital parts of the codec will remain powered up.
This means that the DAI clocks are continue to run, the
oscillator remain operational, etc.

Use the SND_SOC_DAPM_POST_PMD widget to get notification
about the stopped stream, and power down the digital
part of the codec.
If the analog bypass is enabled, than the codec will remain in
BIAS_ON level, and things will work correctly.
In case, if the bypass is disabled, than the codec will
fall to BIAS_STANDBY than to BIAS_OFF level, as it used
to.

The digital part of DAC33 is initialized at every stream start
(DAPM_PRE:PRE_PMU event), so subsequent streams (within 5 sec)
will have working DAI.
When the codec is coming out from BIAS_OFF, the full power-up
sequence followed by the same DAPM_PRE widget event will power up
the digital part.

Peter Ujfalusi d534bacd91 ASoC: tpa6130a2: Defer SW enable from power enable
Do not enable the amplifier right after the power has been
restored to the amplifier.
The DAPM_SUPPLY widget turns on the amp early in the DAPM
power walk, and the unmuting of channel happens quite late.
Keeping the amp in SW reset state ensures better muting.
In this way the pop noise coming from other components (codec)
can be filtered out.

from compression. The rbtree compression gives better results than
LZO for both memory and CPU consumption on a map as sparse as this.

Mark Brown ca9aef5072 ASoC: Convert WM8994 to use soc-cache.c cache functions
In the process we convert the driver to read registers one at a time
when initialising the cache. This has the effect of working around
limitations in the sizes of I2C transactions which can be done by some
CPUs. Due to the sparseness of the register map the overhead from this
should be minimual unless I2C transactions are very expensive to start.

Mark Brown 821edd2fb5 ASoC: Add WM8958 microphone detection support
The WM8958 contains an advanced accessory detection feature which allows
detection of up to seven different impedence levels on the microphone
bias output, including detection of video outputs. Since some of the
more involved accessory interfaces may involve noticable interactions
with external components a simple detection scheme is provided by
default with the option to provide custom handling of accessory detect.

Mark Brown d6addcc9d8 ASoC: Add WM8958 Multi-band compressor support
The WM8958 features a multi-band compressor which can be enabled on
any of the AIF inputs. The MBC allows different gains to be applied to
differnt audio bands, providing an improvement in perceived loudness
of the signal by avoiding overdriving the output transducers. This
patch enables support for the MBC.

Mark Brown 3a42315740 ASoC: Initial WM8958 audio configuration
The WM8958 is a WM8994 derivative. This patch merely ensures that some
revision specific configuration for WM8994 is not enabled on WM8994,
additional patches will add support for the new features introduced on
the WM8958.

Mark Brown 11cef5f07b ASoC: Use DC servo startup mode when not doing DCS correction
Devices which do not have a DCS correction applied can use the explicit
DC servo startup mode for optimal startup performance. This most
immediately affects the WM8958.
